By default, the IGMP general query interval is 60 seconds.
A querier ends General Query messages periodically to maintain group memberships on interfaces. If multiple devices on a shared network segment run IGMP on user-side interfaces, ensure consistent querier parameter settings on these devices. Otherwise, IGMP may not run normally.
To change the default configuration:
- For an IGMP querier, run the timer query interval command in the IGMP view or the igmp timer query interval command in the interface view.
- For an IGMP snooping querier, run the igmp snooping query interval interval command in the VLAN view.
